If you can write in description the ideal time of planting the seeds. It would be great help
Iceberg Lettuce is a crisphead lettuce botanically known as Lactuca sativa.
It develops a dense, rounded head composed of overlapping pale-green leaves with a characteristically:
Iceberg lettuce differs from loose-leaf lettuce because the leaves gradually form a compact central head as the plant matures.
F1 hybrid varieties are developed from selected parent lines to provide improved crop uniformity and consistent plant characteristics under suitable growing conditions.
Iceberg lettuce grows best in cool, moist but well-drained conditions and benefits from regular watering during head formation. RHS describes Iceberg as a crisphead lettuce forming tight rounded heads with crisp, moist leaves.
Exact head size, maturity period, colour and yield may vary according to the specific F1 hybrid, growing temperature and crop management.
Iceberg Lettuce is especially suitable for:
The leaves are valued mainly for their:
Crispness, freshness and refreshing texture
For best eating quality, harvest heads while they are:
Firm, compact and fresh
Wash leaves thoroughly before use.
Suitable for growing one Iceberg Lettuce plant.
G-11 Grow Bag – 11 × 10 inch 🔗
Provides additional growing space for one large head.
G-12 Grow Bag – 12 × 12 inch 🔗
Suitable for one well-developed Iceberg Lettuce plant with generous root space.
G-24 Grow Bag – 24 × 12 inch 🔗
Suitable for growing several lettuce plants together while maintaining adequate spacing.
Use fertile, loose and moisture-retentive but well-drained soil.
A practical GREEN GARDENS mix can be:
50% Bhalu Mitti (Sandy Soil) + 50% Vermicompost 🔗
Iceberg Lettuce performs best in soil that:
An approximate soil pH of:
6.0–7.0
is suitable.
RHS recommends moisture-retentive, well-drained soil for lettuce.
Iceberg Lettuce can be:
Sow seeds shallowly at approximately:
0.5–1 cm deep
Lettuce seeds should not be buried deeply.
Cover lightly with fine soil or vermiculite and water gently.
Keep the growing medium consistently moist.
Seeds generally germinate within:
7–14 days
RHS also notes that lettuce seedlings commonly emerge within this period.
Optimal germination is generally around:
15.5°C–20°C
Lettuce seed can germinate poorly when soil temperatures remain above approximately 24°C–25°C, so cooler sowing conditions are important.
After germination, provide:
Avoid excessive heat.
Seedlings should develop compact growth rather than becoming tall and stretched.
For head lettuce, seedlings are commonly transplanted approximately:
3–4 weeks after sowing
once they are well established.
Transplant carefully to avoid damaging roots.
Water immediately after transplanting.
Avoid planting seedlings too deeply; keep the crown slightly above soil level.
Provide approximately:
5–7 hours of direct sunlight daily
Iceberg lettuce performs well in an open, sunny position during cool weather. RHS lists full sun as the preferred position.
In warmer periods, light afternoon shade may help reduce heat stress and premature bolting.
For full-size Iceberg heads, maintain approximately:
25–30 cm between plants
Commercial head-lettuce recommendations commonly use around 10–12 inches between plants.
Maintain approximately:
35–45 cm between rows
where growing in open beds.
Proper spacing allows enough room for full head development.
Keep the soil consistently moist.
Iceberg Lettuce requires regular moisture for:
Avoid allowing plants to repeatedly wilt.
At the same time, do not keep the soil continuously waterlogged.
Before sowing or transplanting, incorporate GREEN GARDENS Vermicompost 🔗.
Lettuce benefits from fertile soil because it develops rapidly during cool weather.
Balanced nutrition supports healthy leafy growth.
Avoid excessive fertilization.
As Iceberg Lettuce matures, the central leaves gradually overlap and develop into a:
Compact, firm, rounded head
Consistent cool temperatures, sufficient moisture and proper spacing are important for good head formation.
Very warm weather can reduce head quality.
Bolting occurs when lettuce begins producing a flower stalk instead of maintaining leafy growth.
Bolting may be triggered by:
RHS notes that dry summer conditions can increase the risk of bolting.
Maintain regular watering and grow Iceberg primarily during Pakistan's cool season.
Apply a light organic mulch around established plants.
Mulching helps:
Keep mulch slightly away from the crown.
Inspect plants regularly for:
RHS identifies slugs, snails, root aphids, grey mould and downy mildew among potential lettuce problems.
Maintain good airflow and avoid keeping leaves continuously wet.
Harvest the complete head once it becomes:
Firm, rounded and compact
Cut the head cleanly near the base using a sharp knife.
Do not delay harvest excessively once the head has reached usable size because quality may decline and bolting risk increases.
Exact maturity varies according to the specific F1 hybrid, but Iceberg lettuce commonly requires approximately:
55–80 days
depending on whether maturity is counted from transplanting or direct sowing and on prevailing temperatures.
